I BUTTON-FASTENER.

SPECIFICATION forming part of Letters Patent No. &52,138, dated May 12, 1891.

Application filed February 7, 1890. Serial No. 339,605. (No model.)

To all whom it may oowern:

Be it known that I, THEoPHILUs R. HYDE, Jr., of Waterbury, in the county of New I-Ia- Ven and State of Connecticut, have invented a new Improvement in Button-Fasteners; and I do hereby declare the following,when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this speeification, and represent, in

Figure1,a sectional View of one form which a button embodying my invention may assume; Fig. 2, a similar View of the buttonhead and button-fastener assembled preparatory to being Secured together; Fig. 3, a detached sectional View of the cap of the button-head; Fig. 4, a detached perspective View of the re-enforce; Fig. 5, a plan View thereof; Fig. 6, a detached sectional View ot' the back of the button-head; Fig. 7, a detached View of the button-fastener. V

My invention relates to an improvement in that class of buttons in which the buttonfastener is provided with one or more' prongs, which are upset or curled over by an anvil located within the button-head, the object of my present invention being to provide a reenforee for the prongs of 'the fastener, whereby they secure additional grip upon the button-head.

With these ends in View my invention consists in a re-enforce located in the buttonhead and adapted to support the prongs of the fastener and in certain details of construction, as will be hereinatter described, and pointed out in the claim.

As shown in Figs. 1, 2, 4, and 5, my re-enforce has the form of a hollow fluted truncated cone A and is made of sheet metal. It is located within the button-head and interposed between the anvil B of the cap C and the shank D of the back E thereof. The said button-head is of usual Construction, and I neither claim it broadly, nor do I limit myself to it. The button-fastener, as herein shown, consists of a staple F and a two-part head G,

and this I do not claim, except in combination. If desired, it may have more than two prongs. V

In securing the button-head and buttonfastener together the said parts are assenbled, as shown by Fig. 2 of the drawings, in which the stapleprongs are shown to be passed through the fabric and entered into the button-shank and into the re-enforce. Then when they are forced together the staple-prongs are deflected by the tapering sides of the anvil and are curled outward over the edges of the smaller end of the re-enforce, the fiutes or corrugations whereof form guides for the prongs. When the said parts are assembled, as shown by Fig. 1, the re-enforce in part supports the prongs,which are wedged between its upper edge and the tapering sides of the anvil, whereas heretofore the strain tending to separate the head and fastener has been borne entirely by the ends of the prongs at the points where they were engaged with the back of the button-head.

I would have it understood that I do not limit myself to the exact Construction shown and described, but hold myself at liberty. to make such changes and alterations as fairly fall within the spirit and scope of my inven-' tion.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of a button back provided with an anvil, a button-fastener having prongs which are turned over between the said anvil and back, and an independent reenforce interposed between the said anvil and back and consisting of a hollow truncated cone of sheet metal, fiuted to guide and direct the button-fastener prongs which pass through it and which itsupports, substantially as described.
